We look at the division of 85863264 by 399 
We're looking to find how many times 399 goes into 85863264.

Let's proceed to step 1:
399 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 399

Let's proceed to step 2:
When dividing 85 by 399, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 399

Moving on to step 3:
399 can be fit into 858 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 798 from 858 leaves us with 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 399

Let's proceed to step 4:
If we divide 606 by 399, we get 1 and a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 399 from 606, we get 207.
Grab the next digit (3) from the dividend, add it to 207, then carry on: 2073 / 399

Step 5:
2073 divided by 399 is 5 with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtract 1995 from 2073 to get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 399

Advancing to step 6:
The number 399 fits into 782 1 times, leaving a remainder of 383.
The next digit of our result is 1. 
Result so far: 2151.0
If we subtract 399 from 782, we get 383.
Append the next digit (6) from the dividend to 383 and continue with: 3836 / 399

On to step 7:
If we divide 3836 by 399, we get 9 and a remainder of 245.
Put 9 as the next digit of the answer. 
Result so far: 21519.0
Deduct 3591 from 3836 and we're left with 245.
Grab the next digit (4) from the dividend, add it to 245, then carry on: 2454 / 399

On to step 8:
If we divide 2454 by 399, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 215196.0
Subtracting 2394 from 2454 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 399, we get 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 215196.1
Subtracting 399 from 600 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
2010 divided by 399 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 215196.15
If we take 1995 away from 2010, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 399 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 215196.15
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
399 can be fit into 1500 3 times, resulting in a remainder of 303.
Put 3 as the next digit of the answer. 
Result so far: 215196.1503
If we take 1197 away from 1500, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 13:
399 can be fit into 3030 7 times, resulting in a remainder of 237.
Write down 7 as next digit of the result. 
Result so far: 215196.15037
If we subtract 2793 from 3030, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 14:
399 can be fit into 2370 5 times, resulting in a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 215196.150375
If we subtract 1995 from 2370, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 15:
If we divide 3750 by 399, we get 9 and a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 215196.1503759
Deduct 3591 from 3750 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 16:
399 goes into 1590 3 times with a remainder of 393.
The number 3 becomes the next digit in our result. 
Result so far: 215196.15037593
Subtract 1197 from 1590 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

The final result is 215196.15037593 with a remainder of 3.93e-07.
